Can the Intel Arc B580 12GB run Prithvi WxC?

Yes โ€” here's how fast and up to what context, with real measured numbers.

Prithvi WxC on the Intel Arc B580 12GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 75k 57.5-71.4 t/s ~5-6.3 (slow)
Q8 yes 110k 115-142.7 t/s ~10.1-12.5 (slow)
Q4 yes 126k 205.3-254.9 t/s ~18-22.4 (slow)

Estimate (memory-bound). Beyond "max context" the KV cache spills to system RAM offload (depends on your system RAM) and speed drops to the "beyond" figure.

FAQ

Can the Intel Arc B580 12GB run Prithvi WxC?โ–ถ

Yes. At Q4 it generates ~205.3-254.9 tok/s and fits up to 126k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~18-22.4 tok/s.

How much context fits?โ–ถ

At Q4, up to about 126k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
